FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication and to techniques and apparatuses for channel stateinformation processing unit occupancy for layer 1 signal to interferenceplus noise ratio reporting.

DESCRIPTION OF RELATED ART

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, and/or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations(BSs) that can support communication for a number of user equipment(UEs). A user equipment (UE) may communicate with a base station (BS)via the downlink and uplink. The downlink (or forward link) refers tothe communication link from the BS to the UE, and the uplink (or reverselink) refers to the communication link from the UE to the BS. As will bedescribed in more detail herein, a BS may be referred to as a Node B, agNB, an access point (AP), a radio head, a transmit receive point (TRP),a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. New Radio (NR), which may also bereferred to as 5G, is a set of enhancements to the LTE mobile standardpromulgated by the Third Generation Partnership Project (3GPP). NR isdesigned to better support mobile broadband Internet access by improvingspectral efficiency, lowering costs, improving services, making use ofnew spectrum, and better integrating with other open standards usingorthogonal frequency division multiplexing (OFDM) with a cyclic prefix(CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g.,also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) onthe uplink (UL), as well as supporting beamforming, multiple-inputmultiple-output (MIMO) antenna technology, and carrier aggregation.However, as the demand for mobile broadband access continues toincrease, there exists a need for further improvements in LTE and NRtechnologies. Preferably, these improvements should be applicable toother multiple access technologies and the telecommunication standardsthat employ these technologies.

This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based on theteachings herein one skilled in the art should appreciate that the scopeof the disclosure is intended to cover any aspect of the disclosuredisclosed herein, whether implemented independently of or combined withany other aspect of the disclosure.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, and/or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

It should be noted that while aspects may be described herein usingterminology commonly associated with 3G and/or 4G wireless technologies,aspects of the present disclosure can be applied in othergeneration-based communication systems, such as 5G and later, includingNR technologies.

FIG. 1 is a diagram illustrating a wireless network 100 in which aspectsof the present disclosure may be practiced. The wireless network 100 maybe an LTE network or some other wireless network, such as a 5G or NRnetwork. The wireless network 100 may include a number of BSs 110 (shownas BS 110 a, BS 110 b, BS 110 c, and BS 110 d) and other networkentities. ABS is an entity that communicates with user equipment (UEs)and may also be referred to as a base station, a NR BS, a Node B, a gNB,a 5G node B (NB), an access point, a transmit receive point (TRP),and/or the like. Each BS may provide communication coverage for aparticular geographic area. In 3GPP, the term “cell” can refer to acoverage area of a BS and/or a BS subsystem serving this coverage area,depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). ABS for a macro cell may bereferred to as a macro BS. A BS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1 , a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. A BS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in thewireless network 100 through various types of backhaul interfaces suchas a direct physical connection, a virtual network, and/or the likeusing any suitable transport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1 , a relay station 110 d may communicate with macro BS 110 a and aUE 120 d in order to facilitate communication between BS 110 a and UE120 d. A relay station may also be referred to as a relay BS, a relaybase station, a relay, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 Watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, e.g., directly or indirectly via a wireless orwireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, and/or the like. A UE may be a cellularphone (e.g., a smart phone), a personal digital assistant (PDA), awireless modem, a wireless communication device, a handheld device, alaptop computer, a cordless phone, a wireless local loop (WLL) station,a tablet, a camera, a gaming device, a netbook, a smartbook, anultrabook, a medical device or equipment, biometric sensors/devices,wearable devices (smart watches, smart clothing, smart glasses, smartwrist bands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, location tags, and/or the like, that may communicate with abase station, another device (e.g., remote device), or some otherentity. A wireless node may provide, for example, connectivity for or toa network (e.g., a wide area network such as Internet or a cellularnetwork) via a wired or wireless communication link. Some UEs may beconsidered Internet-of-Things (IoT) devices, and/or may be implementedas NB-IoT (narrowband internet of things) devices. Some UEs may beconsidered a Customer Premises Equipment (CPE). UE 120 may be includedinside a housing that houses components of UE 120, such as processorcomponents, memory components, and/or the like.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT may also be referred to asa radio technology, an air interface, and/or the like. A frequency mayalso be referred to as a carrier, a frequency channel, and/or the like.Each frequency may support a single RAT in a given geographic area inorder to avoid interference between wireless networks of different RATs.In some cases, NR or 5G RAT networks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure(V2I) protocol, and/or the like), a mesh network, and/or the like. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1 .

FIG. 2 shows a block diagram of a design 200 of base station 110 and UE120, which may be one of the base stations and one of the UEs in FIG. 1. Base station 110 may be equipped with T antennas 234 a through 234 t,and UE 120 may be equipped with R antennas 252 a through 252 r, where ingeneral T≥1 and R≥1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI) and/or the like) and controlinformation (e.g., CQI requests, grants, upper layer signaling, and/orthe like) and provide overhead symbols and control symbols. Transmitprocessor 220 may also generate reference symbols for reference signals(e.g., the cell-specific reference signal (CRS)) and synchronizationsignals (e.g., the primary synchronization signal (PSS) and secondarysynchronization signal (SSS)). A transmit (TX) multiple-inputmultiple-output (MIMO) processor 230 may perform spatial processing(e.g., precoding) on the data symbols, the control symbols, the overheadsymbols, and/or the reference symbols, if applicable, and may provide Toutput symbol streams to T modulators (MODs) 232 a through 232 t. Eachmodulator 232 may process a respective output symbol stream (e.g., forOFDM and/or the like) to obtain an output sample stream. Each modulator232 may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively. According to variousaspects described in more detail below, the synchronization signals canbe generated with location encoding to convey additional information.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110 and/or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (e.g., filter, amplify,downconvert, and digitize) a received signal to obtain input samples.Each demodulator 254 may further process the input samples (e.g., forOFDM and/or the like) to obtain received symbols. A MIMO detector 256may obtain received symbols from all R demodulators 254 a through 254 r,perform MIMO detection on the received symbols if applicable, andprovide detected symbols. A receive processor 258 may process (e.g.,demodulate and decode) the detected symbols, provide decoded data for UE120 to a data sink 260, and provide decoded control information andsystem information to a controller/processor 280. A channel processormay determine reference signal received power (RSRP), received signalstrength indicator (RSSI), reference signal received quality (RSRQ),channel quality indicator (CQI), and/or the like. In some aspects, oneor more components of UE 120 may be included in a housing.

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to basestation 110. At base station 110, the uplink signals from UE 120 andother UEs may be received by antennas 234, processed by demodulators232, detected by a MIMO detector 236 if applicable, and furtherprocessed by a receive processor 238 to obtain decoded data and controlinformation sent by UE 120. Receive processor 238 may provide thedecoded data to a data sink 239 and the decoded control information tocontroller/processor 240. Base station 110 may include communicationunit 244 and communicate to network controller 130 via communicationunit 244. Network controller 130 may include communication unit 294,controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform one ormore techniques associated with channel state information processingunit occupancy for layer 1 signal to interference plus noise ratioreporting, as described in more detail elsewhere herein. For example,controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform or directoperations of, for example, process 400 of FIG. 4 and/or other processesas described herein. Memories 242 and 282 may store data and programcodes for base station 110 and UE 120, respectively. In some aspects,memory 242 and/or memory 282 may comprise a non-transitorycomputer-readable medium storing one or more instructions for wirelesscommunication. For example, the one or more instructions, when executedby one or more processors of the base station 110 and/or the UE 120, mayperform or direct operations of, for example, process 400 of FIG. 4and/or other processes as described herein. A scheduler 246 may scheduleUEs for data transmission on the downlink and/or uplink.

In some aspects, UE 120 includes means for receiving a CSI reportingconfiguration for a CSI report, wherein the CSI reporting configurationindicates that the CSI report is to include L1-SINR; means fordetermining a number of CPUs occupied for processing of the CSI reportthat is to include the L1-SINR; and/or the like. In some aspects, the UE120 includes means for selectively updating the CSI report based atleast in part on the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR. In some aspects, such means mayinclude one or more components of UE 120 described in connection withFIG. 2 , such as controller/processor 280, transmit processor 264, TXMIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256,receive processor 258, and/or the like.

As indicated above, FIG. 2 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 2 .

When determining whether to update channel state information (CSI), a UEmay determine a CSI processing unit (CPU) occupancy for a CSI report,denoted as O_(CPU) ^((n)) for a CSI report n. The UE may be capable of anumber (e.g., a maximum number) of simultaneous CSI calculations,denoted as N_(CPU). Additionally, or alternatively, the value of N_(CPU)may indicate a number (e.g., a maximum number) of CPUs that the UE iscapable of using to process CSI report across all configured cells. Insome aspects, the UE may report the value of N_(CPU) to a base station,such as in a UE capability report. If L CPUs of the UE are occupied in agiven OFDM symbol, then the UE 120 may have N_(CPU) minus L (N_(CPU)−L)unoccupied CPUs (e.g., CPUs available for performing a CSI calculationand/or processing a CSI report) in the OFDM symbol.

When performing CSI processing, the UE may drop one or more low priorityCSI reports if the UE does not have enough available CPUs to process allCSI reports in a given OFDM symbol. Each CSI report n configured for theUE may be associated with a CPU occupancy O_(CPU) ^((n)). Furthermore,each CSI report may be associated with a priority. In some cases,different CSI reports may be associated with different CPU occupanciesand/or different priorities. Depending on the CPU occupancy of the CSIreports configured for the UE and/or requested by the base station, theUE is not required to update N minus M (N−M) requested CSI reports withthe lowest priority (as compared to the other requested CSI reports,where:Σ_(n=0) ^(M) O _(CPU) ^((n)) ≤N _(CPU) −L

In other words, the UE may determine whether the UE has sufficient CPUsavailable (e.g., unoccupied) in an OFDM symbol to process a highestpriority CSI report based at least in part on a CPU occupancy of thehighest priority CSI report. If the UE has sufficient CPUs available inthe OFDM symbol to process the highest priority CSI report, then the UEmay determine whether the UE has sufficient CPUs available in the OFDMsymbol (after considering the CPUs needed to process the highestpriority CSI report) to process a second-highest priority CSI reportbased at least in part on a CPU occupancy of the second-highest priorityCSI report. If the UE has sufficient CPUs available in the OFDM symbolto process the highest priority CSI report and the second-highestpriority CSI report, then the UE may determine whether the UE hassufficient CPUs available in the OFDM symbol (after considering the CPUsneeded to process the highest priority CSI report and the second-highestpriority CSI report) to process a third-highest priority CSI reportbased at least in part on a CPU occupancy of the third-highest priorityCSI report, and so on. When the UE determines that the UE does not havesufficient CPUs available in the OFDM symbol for a given CSI report,then the UE may refrain from performing CSI processing for the CSIreport (e.g., may refrain from updating CSI for the given CSI report)and for any other CSI reports having a lower priority than the given CSIreport. In this case, the UE may transmit previously-determined CSI inthe CSI report (e.g., without updating the CSI).

In NR, layer 1 signal to interference plus noise ratio (L1-SINR) hasbeen added as a value that can be reported in a CSI report. Due to thenature of L1-SINR derivation and processing, several different CPUoccupancy values could be used for CSI reports that include L1-SINR.Some techniques and apparatuses described herein enable a UE todetermine a CPU occupancy to be used for CSI reports that includeL1-SINR.

FIG. 3 is a diagram illustrating an example of channel state informationprocessing unit occupancy for layer 1 signal to interference plus noiseratio reporting, in accordance with various aspects of the presentdisclosure. As shown in FIG. 3 , a base station 110 and a UE 120 maycommunicate with one another.

As shown by reference number 305, the base station 110 may transmit, tothe UE 120, a CSI reporting configuration for a CSI report. The CSIreporting configuration may indicate that the CSI report is to includeL1-SINR. In some aspects, the CSI reporting configuration may beincluded in a radio resource control (RRC) message, such as an RRCconfiguration message, an RRC reconfiguration message, and/or the like.In some aspects, a CSI reporting configuration (CSI-ReportConfig) for aCSI report may include a report quantity (report Quantity) informationelement or parameter that indicates the quantities or parameters thatare to be reported in the CSI report. In some aspects, the reportquantity IE may indicate that an L1-SINR parameter is to be included inthe CSI report, such as by including a value of ‘cri-SINR’,‘ssb-Index-SINR’, and/or the like. Additionally, or alternatively, thereport quantity IE may indicate one or more other parameters that are tobe reported in the CSI report (e.g., the same CSI report as theL1-SINR), such as a rank indication (RI) parameter, a channel qualityindication (CQI) parameter, a precoding matrix indication (PMI)parameter, a reference signal received power (RSRP) parameter, a layerindication (LI) parameter, and/or the like. For example, the reportquantity IE may include a value of ‘cri-RI-PMI-CQI’, ‘cri-RI-i1’,‘cri-RI-i1-CQI’, ‘cri-RI-CQI’, ‘cri-RSRP’, ‘ssb-Index-RSRP’,‘cri-RI-LI-PMI-CQI’, and/or the like.

In some aspects, the UE 120 may indicate a UE capability for a number(e.g., a maximum number) of CPUs for processing CSI reports across allconfigured cells, sometimes referred to as a UE capability for a number(e.g., a maximum number) of simultaneous CSI calculations, either orboth of which may be denoted as N_(CPU). In some aspects, the UE 120 maytransmit the UE capability in a UE capability report (e.g., prior toreceiving the CSI reporting configuration, in some aspects).

As shown by reference number 310, the base station 110 may transmit, tothe UE 120, a request for a CSI report (e.g., a CSI request). In someaspects, the request is a request for a periodic CSI report. In thiscase, the base station 110 may indicate a periodicity and/or a set ofuplink resources for transmission of the CSI report, a periodicityand/or a set of downlink resources for reference signals (e.g., channelstate information reference signals (CSI-RSs), synchronization signalblocks (SSBs), and/or the like) to be measured by the UE 120 for the CSIreport, and/or the like. In some aspects, the request is a request foraperiodic CSI. In this case, the base station 110 may indicate a set ofuplink resources for transmission of the CSI report, a set of downlinkresources for reference signals (e.g., CSI-RSs, SSBs, and/or the like)to be measured by the UE 120 for the CSI report, and/or the like. Insome aspects, the request may be included in an RRC message, such as thesame RRC message that includes the CSI reporting configuration.Additionally, or alternatively, the request may be included in downlinkcontrol information (DCI), a medium access control (MAC) control element(CE), and/or the like.

As shown by reference number 315, the UE 120 may determine a number ofCSI processing units (CPUs) occupied for processing of the CSI reportthat is to include the L1-SINR. In some aspects, the number of CPUsoccupied for processing of a CSI report that is to include L1-SINR maybe prespecified according to a wireless communication standard.Additionally, or alternatively, the UE 120 may determine the number ofCPUs occupied for processing of a CSI report that is to include L1-SINRbased at least in part on a rule. The rule may be prespecified accordingto a wireless communication standard and/or may signaled to the UE 120in a configuration message. Additionally, or alternatively, the UE 120may determine the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR based at least in part onreceiving the request for the CSI report.

In some aspects, the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR is zero. For example, the UE 120may derive L1-SINR from one or more reference signals (e.g., aninterference signal) and/or one or more parameters (e.g., RSRP). The UE120 may be capable of receiving such signal(s) and/or determining suchparameter(s) prior to the OFDM symbol associated with processing of theCSI report. Additionally, or alternatively, deriving L1-SINR from thesesignal(s) and/or parameter(s) may not be resource intensive. Thus, thenumber of CPUs occupied for processing of the CSI report that is toinclude the L1-SINR may be set equal to zero.

In some aspects, the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR is one. In this case, the numberof CPUs occupied for processing (e.g., deriving, calculations, and/orthe like) L1-SINR may be equal to the number of CPUs occupied forprocessing RSRP.

In some aspects, the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR is equal to a UE capability for anumber (e.g., a maximum number, a reported number, and/or the like) ofCPUs for processing CSI reports across all configured cells and/or a UEcapability for a number (e.g., a maximum number, a reported number,and/or the like) of simultaneous CSI calculations. In this case, thenumber of CPUs occupied for processing (e.g., deriving, calculations,and/or the like) L1-SINR may be equal to the value of N_(CPU) reportedby the UE 120 to the base station 110 (e.g., in a UE capability report).

In some aspects, the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR is equal to the UE capability forthe number of CPUs for processing CSI reports across all configuredcells if (e.g., when) a condition is satisfied. In some aspects, thecondition is that the CSI report is aperiodically triggered withouttransmitting a physical uplink shared channel (PUSCH) that includes atleast one of a transport block (TB) or hybrid automatic repeat requestacknowledgement (HARQ-ACK) feedback (e.g., that includes a TB, HARQ-ACKfeedback, or both) when no CPUs are occupied (e.g., L=0 CPUs areoccupied), where the CSI corresponds to a single CSI with widebandfrequency granularity and to at most 4 CSI-RS ports in a single resourcewithout a CSI-RS resource indicator (CRI) report and where a codebooktype (codebookType) is set to ‘typeI-SinglePanel’. Additionally, oralternatively, the condition may be that the CSI report is to alsoinclude at least one of a CQI parameter or a PMI parameter.

In some aspects, the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR is equal to a number of CSI-RSs ina CSI-RS resource set for channel measurement associated with the CSIreport. The number of CSI-RSs in a CSI-RS resource set for channelmeasurement associated with the CSI report may be denoted as K_(s). Insome aspects, the number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR is equal to the number of CSI-RSsin the CSI-RS resource set for channel measurement associated with theCSI report if (e.g., when) one or more of the conditions described inthe previous paragraph is not satisfied. For example, in some aspects,the number of CPUs occupied for processing of the CSI report that is toinclude the L1-SINR is equal to the number of CSI-RSs in the CSI-RSresource set for channel measurement associated with the CSI report if(e.g., when) the CSI report is not aperiodically triggered withouttransmitting a physical uplink shared channel (PUSCH) that includes atleast one of a transport block (TB) or hybrid automatic repeat requestacknowledgement (HARQ-ACK) feedback when no CPUs are occupied, where theCSI corresponds to a single CSI with wideband frequency granularity andto at most four channel state information reference signal (CSI-RS)ports in a single resource without a CSI-RS resource indicator (CRI)report, and where a codebook type (codebookType) is set to‘type1-SinglePanel’. Additionally, or alternatively, the number of CPUsoccupied for processing of the CSI report that is to include the L1-SINRis equal to the UE capability for the number of CPUs for processing CSIreports across all configured cells if (e.g., when) the CSI report doesnot include a CQI parameter and does not include a PMI parameter.

In some aspects, the UE 120 may determine the number of CPUs occupiedfor processing of the CSI report that is to include the L1-SINR based atleast in part on an L1-SINR measurement resource configuration. In someaspects, the L1-SINR measurement resource configuration may be indicatedin a configuration message, such as an RRC message. Additionally, oralternatively, the L1-SINR measurement resource configuration may beindicated in a request that schedules the CSI report. The L1-SINRmeasurement resource configuration may indicate whether L1-SINR is to bemeasured on channel measurement resources (CMRs), whether L1-SINR is tobe measured on interference measurement resources (IMRs) (e.g., whetherdedicated IMRs are configured for L1-SINR measurements), whether CSI-RSsare to be used for the CMRs (e.g., whether CSI-RS-based CMR is to beused, such as with a density of 3 resource elements (REs) per resourceblock (RB)), whether SSBs are to be used for the CMRs (e.g., whetherSSB-based CMR is to be used), whether zero power (ZP) IMRs are to beused, whether non-zero power (NZP) IMRs are to be used (e.g., with adensity of 3 REs per RB), and/or the like.

In some aspects, the L1-SINR measurement resource configurationindicates that L1-SINR is to be measured on only CMRs and not on IMRs(e.g., that dedicated IMRs are not configured for L1-SINR measurements).In some aspects (e.g., if the L1-SINR measurement resource configurationindicates that L1-SINR is to be measured on only CMRs and not on IMRs),the L1-SINR measurement resource configuration may indicate CSI-RSs forthe CMRs (e.g., may indicate CSI-RS-based CMRs). In some aspects,CSI-RS-based CMRs may have a density of 3 REs per RB.

In some aspects, the L1-SINR measurement resource configurationindicates that L1-SINR is to be measured on both CMRs and on IMRs (e.g.,that dedicated IMRs are configured for L1-SINR measurements). Forexample, in some aspects, the L1-SINR measurement resource configurationmay indicate SSBs for the CMRs (e.g., SSB-based CMRs) and may indicateZP IMRs. In some aspects, the L1-SINR measurement resource configurationmay indicate CSI-RSs for the CMRs (e.g., CSI-RS-based CMRs) and mayindicate ZP IMRs. In some aspects, the L1-SINR measurement resourceconfiguration may indicate SSBs for the CMRs (e.g., SSB-based CMRs) andmay indicate NZP IMRs (e.g., with a density of 3 REs per RB). In someaspects, the L1-SINR measurement resource configuration may indicateCSI-RSs for the CMRs (e.g., CSI-RS-based CMRs) and may indicate NZP IMRs(e.g., with a density of 3 REs per RB). In some aspects, the L1-SINRmeasurement resource configuration may indicate SSBs for the CMRs (e.g.,SSB-based CMRs) and may indicate both ZP and NZP IMRs. In some aspects,the L1-SINR measurement resource configuration may indicate CSI-RSs forthe CMRs (e.g., CSI-RS-based CMRs) and may indicate both ZP and NZPIMRs.

In some aspects, for a given L1-SINR measurement resource configuration,the UE 120 may determine the number of CPUs occupied for processing ofthe CSI report that is to include the L1-SINR. For a given L1-SINRmeasurement resource configuration, the number of CPUs may be equal tozero, one, N_(CPU), or K_(s), as described elsewhere herein. In someaspects, different L1-SINR measurement resource configurations may beassociated with different numbers of CPUs occupied for processing of theCSI report that is to include the L1-SINR. In some aspects, the numberof CPUs for an L1-SINR measurement resource configuration may beprespecified according to a wireless communication standard.

As shown by reference number 320, the UE 120 may selectively update theCSI report (and/or one or more other CSI reports) based at least in parton the determined number of CPUs occupied for processing of the CSIreport that is to include the L1-SINR. For example, if the UE 120 hassufficient CPUs available in an OFDM symbol to process the CSI report,then the UE 120 may update CSI for the CSI report, such as by performingCSI calculations (e.g., in the OFDM symbol). In this case, the UE 120may include the updated CSI in the CSI report, and may transmit the CSIreport to the base station 110. If the UE 120 does not have sufficientCPUs available in an OFDM symbol to process the CSI report, then the UE120 may not update CSI for the CSI report, such as by refraining fromperforming CSI calculations (e.g., in the OFDM symbol). In this case, insome aspects, the UE 120 transmit previously-determined CSI in the CSIreport (e.g., previously-determined CSI that was transmitted in aprevious CSI report), and may transmit the CSI report to the basestation 110. Alternatively, the UE 120 may drop the CSI report. In thisway, the UE 120 may appropriately determine a CPU occupancy to be usedfor CSI reports that include L1-SINR, and may selectively update CSIreports accordingly.
